Checking MCSG

[Vijaya Kumar_3]

Hi all
I am new to MCSG and i need a help from you. I am writing a shell script and need to check whether MC Serviceguard is installed or not. Based on that i need to run some task.
anyone help me how can i check whether MCSG is installed and working in this machine.
I know i can check the installation with swlist | grep -i serviceguard but i need to know whether it is part of a running cluster.
Thanks
Vijay

If you need to check for a running cluster node then grep'ing the cmviewcl output could be a way to go. You could also check if the cluster damon 'cmcld' is present.

Best regards...

Hi,

# swlist ServiceGuard

will tell u if it has been installed or not

# ps -ef | grep /usr/lbin/cmcld | grep -v grep | grep -q cmcld
# if [[ $? -ne 0 ]]
then
echo "cluster not running"
else
echo "running"
fi

Thanks,

Sundar.

a.) Regarding "...check whether MC Serviceguard is installed or not..."

# swlist -l fileset -a state | grep -i serviceguard

b) Regarding "..and working in this machine..."

This will be a combo of things depending on what you want, for many SA's don't allow the SG cluster to start at boot up. If you do then:

- grep "AUTOSTART_CMCLD=1" /etc/rc.config.d/cmcluster

- Check syslog.log for 'vmunix' and 'cmcld' messages.

- ServiceGuard Manager, a free openview download from:

- or do as others have suggested and parse the output of 'cmviewcl -v'.

# cmclview -v > /tmp/file
# grep -i -e enabled -e primary /tmp/file (* etc. *)
